We look at the division of 13025512 by 488 
The aim is to understand the frequency of 488 in 13025512.

Step 1:
When dividing 1 by 488, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 488

Moving on to step 2:
If we divide 13 by 488, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 488

Going ahead to step 3:
The number 488 fits into 130 0 times, leaving a remainder of 130.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 130 leaves us with 130.
Append the next digit (2) from the dividend to 130 and continue with: 1302 / 488

Going ahead to step 4:
If we divide 1302 by 488, we get 2 and a remainder of 326.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 326 after subtracting 976 from 1302.
Bring next digit (5) of the dividend behind the 326 and repeat the process: 3265 / 488

Moving on to step 5:
The number 488 fits into 3265 6 times, leaving a remainder of 337.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 2928 from 3265, we get 337.
Include the next digit (5) from the dividend after 337, then repeat: 3375 / 488

On to step 6:
If we divide 3375 by 488, we get 6 and a remainder of 447.
Put 6 as the next digit of the answer. 
Result so far: 266.0
If we take 2928 away from 3375, we end up with 447.
Grab the next digit (1) from the dividend, add it to 447, then carry on: 4471 / 488

Step 7:
When dividing 4471 by 488, we get 9 with a remainder of 79.
The next digit of our result is 9. 
Result so far: 2669.0
Subtract 4392 from 4471 to get 79.
Append the next digit (2) from the dividend to 79 and continue with: 792 / 488

Going ahead to step 8:
792 divided by 488 is 1 with a remainder of 304.
Write down 1 as next digit of the result. 
Result so far: 26691.0
The remainder is 304 after subtracting 488 from 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 9:
If we divide 3040 by 488, we get 6 and a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 26691.6
The remainder is 112 after subtracting 2928 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 10:
488 can be fit into 1120 2 times, resulting in a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 26691.62
Subtracting 976 from 1120 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 11:
When dividing 1440 by 488, we get 2 with a remainder of 464.
Put 2 as the next digit of the answer. 
Result so far: 26691.622
Subtract 976 from 1440 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The final outcome is 26691.622, with a leftover of 0.0464.
